Redirect to a wrong url when a model of singular resource gets updated

Profile updating redirects to a wrong URL with the original user id.

The URL of profile has users/user's_random_id/profile and after I edit and update it on
users/user's_random_id/profile/edit, it redirects to users/id/profile.

For example, users/abcdef/profile/edit redirects to users/1/profile after updating.
"abdef" and 1 are actually the same object so it’s almost correct but I want "abcdef." I want it to redirect to users/abcdef/profile/ after updating.

The profile model belongs to the user model.

The user has to_param and it works well for its controllers.

The route

resources :users, param: :random_id do
    member do
      resource  :profile,    only: [:show, :edit, :update]
    end
end

Profile controller

  def show
    # @user = User.find_by(id: params[:id])
    @user = User.find_by(random_id: params[:random_id])
    
    @profile = @user.profile
  end

  def update
    @user = User.find_by(random_id: params[:random_id])
    @profile = @user.profile


    if @profile.update(profile_params)
      @profile.update(age: @profile.get_age)
      flash[:success] = "Profile updated"
      redirect_to user_profile_path
    else
      render 'edit'
    end
  end

class User < ApplicationRecord
  def to_param
    random_id
  end

  # or
  alias_method :to_param, :random_id
end

resources :users, param: :random_id
